[TriEmbed] Fw: Question concerning a mechanical release

[John Vaughters]

Interesting question with many details missing, but I will give it a shot. Using a pinching clamp, say like a sail boat type clamp, but have a solenoid that would release the clamp on demand of your software. A pinching clamp would hold it's own weight in the since that the more weight you put on the string the harder it clamps. at least one side of the clamp rotates and this would allow you to attach a solenoid to it and rotate it away from the string thereby releasing it.


Here is an example of a cam cleat used on sailboats. You could use the idea and make one side stationary and the other rotate and connected to a solenoid.

Good Luck!

I am trying to make something that would achieve the following end:

raspberry pi being able to release a weight on a string. 

My idea was that the pi could send a signal to disengage some kind of clamp and release the weight, but I am not sure what kind of clamp or what I should use here?

Does anyone have any better ideas how to release a weight on a string controlled by a pi? 

Thanks, I can't attend this meeting because of my courseload, but I still want to participate in general discussions.
